TOM'S TIPS

Ihe first, and probably the last, of an occasional series of technical tips

My Yaesu FT 840 transceiver developed an intermittent fault on transmit ssb but was always ok on3W.

Ihe fault proved to be a loose key jack on the main circuit board. The insertion of the key plugnormal$ disables the ssb so that one can't leave it in permanently.

Oonstantly pulling the plug out of the rear of the rig can loosen the jack.

Ihe solution was to lift the main circuit board after removing five screws, a few plugs and the rearranel so that it could be raised sufficiently to resolder the jack onto the board

tn the case of the Alinco DX 70T, one is able to leave the cw key permanently connected. Be careful;hough whilst reaching behind your transceiver that you don't pull out the 3.5mm cw key plug to ahalfway position, very easily done! If you are in cw mode, the transceiver will immediately go totransmit. If you are in ssb mode, fine-- until you move through the memories which may contain cwmodes on full power setting! This can result in the destruction. of the PAs in either or both the50Mhz and hf sections.

Another fault which I had on my Yaesu was the almost complete seizure of the main tuning knob,most certainly not through lack of use!

fhe cure for this was as follows.

Pull the knurled rubber ring offthe tuning knob. Locate the hole in the edge of the tuning knob andme a 2mm Allen wrench to loosen the set screw accessible through the hole, just enough to allowfie knob to be pulled offthe shaft. Turn the rig so that the front faces upwards and drip a few dropscf WD40 down between the shaft and its associated bush. This should restore the movement to its

original condition.

J?SGB MORSE TEST.At the present time it is IARU policy ta support the retention of Mandatory Testing and over thecoming months leading up to WRC2001 the Society will, through the offices of the IARU besubmitting papers in an effort to bring the other Society's in line with our thinking on this subject.No changes can be made before the issue has been discussed at WRC because of currentInternational agreements such as CEPT- TR61-01 and TR61-02.However, Council feel that we should move forward on this issue to encourage growth and securethe future of Amateur Radio within the UK.To this end, the Society is in discussions with the RA to secure the introduction of a new interim AllBands Licence which will allow all amateurs access to the FIF bands below 30MHz on attaining aMorse Test speed pass at 5 wpm. The RA support this move andit is hoped that this licence can beintroduced as quickly as possible.This licence will only be for use within the UK. Any amateur wishing to operate in accordance withthe CEPT agreements outside the UK will still be iequired to take f 12 wpm test.So there we go for all you wingers out there no excuses now 5wpm easy as pie......

lslands on the Air

A team from Cockenzie & Port Seton Amateur Radio Club will operate from the beautiful IsleTiree, the most westerly of the Inner Hebridean Islands, during the IOTA ( Islands on the Air )contest, being held from 12.00 UTC on luly 25thuntil 12.00 July 26th 1998.

The team comprising Alex GMOWSN, Cambell MMIAVA' John GMTTKA, John GMTOLQ, IainMMICPP, Wallace MM0AMV, with Fred GMOALS as QSL Manager, will work from Gott Bay onthe east of the Island, using the callsign MM0AMV/P.

iree is some 10 miles long and 3 miles wide, and is skirted by the Hebridean Sea to the South andEast with the Atlantic Ocean to the North and West. The island has no trees, as they cannot rootagainst the severe winter gales, but it is famed for it's spring and summer sunshine records andbirds, flora and fauna not seen on the mainland. A flat crofting land, Tiree has only three hills above300 ft, with a coastline edged with long, windswept, shell sand beaches.

Charger for Lead Acid Baftery

Many of you who purchased lead acid batteries for our charity may be interested in building therequired charger for this type of battery.The circuit is shown below and is a constant voltage chargerwith R5 determining the maximum voltage.(in this case lamp).TRl is any general purpose siliconNPN type.The circuit should be set while in open circuit the value being 13.8V. If the circuit doesnot seem to provide full charging then inrease voltage slightly by adjustment of RVl.IClis an LM317 which is used as a variable voltage regulator via Rl, RVI and R2. However thecurrent is limited when the voltage across R5 exceeds about 0.6Vand TRl begins to turn onlowering the drive current to ICI which adjusts accordingly. The charger will stayin this constantcurrent mode until the battery voltage rises and the current required starts to drop below lA.when itwill revert to a constant voltage mode
